Walkthrough of the loophole-free Bell test performed at NIST

This hyperlapse video shows the three locations used in the loophole-free Bell test performed at NIST. We start at Alice's location where she measures the photons sent from the source. At the source location, entangled pairs of photons are created that are distributed via optical fiber to both Alice and Bob. Finally, the video ends at Bob's location. The photons travel in fibers that are strung up in the ceiling of the corridor of the path walked.
